IMPRDVED METHOD OF MAKING INKSTANDS, 81e.

The Schedule referred to in these Letters Patent and making part of thename.

To all persons to whom these presents may come:

Beit known that I, HENRY WHITNEY, of East Gambridge, in theconnty of Middlesex, and 'State of Massachusetts, have made a new and useful invention, having reference to the Manufacture 'of an Inkstand, or other vessel made of glass, and having its bottom formed of a tube, or tubular` projection, gathered in, or contracted at or near one end-thereof; and I do hereby declare the same .to be fully described in the following specication, and represented in the accompanying drawings, of which- Figure l denotes a vertical section of an inkstand, as made with a contracted tubular projection for its bottom, and in accordance with my invention.

Figure 2 is a similar section of it as it appears preparatory to the contraction oi. the tubular projection for the formation of the bottom.- g Y Figure 3 is a section of an inkstand as usually made prior to my invention, with a tubular projection to be contracted for the formation of the bottom.

Figure'l is a section of such inkstand as it appears after contraction of the tubular projection in order to form the bottom. Y

My improvement will apply to the making of a de-y canter, or bottle, aswell as to various other articles usually constructed of glass'.

In figs. 2 and 3 of such drawings, the body, A, of the glass vessel is represented as moulded with a tubular projection, B, which, afterward, is `to' be heated in a furnace, and by means of a tool, and in a manner well known to glass-makers, is to be contracted and closed together, so as to form the bottom, shown in figs l and 4 at B.

The distinguishing feature of novelty between my mode of forming the article, or vessel with a contrae. tile bottom projection, and that heretofore practised is,

that I make it with an open space, C, circnmscribing the tubular projection, and arranged between such and the base part, D, which extends beyond the bottom..

bottom, and thereby have an uneven bearing on the' supporting-surface.

With my improvement, however, the whole bottom may be readily gathered in' and arranged so far above the base of the body as not to prevent the lower edge of such base from coming into full contact with the surface on which it may be placed.

I therefore make no claiml to moulding a glass vessel with a tubular-proj ection to extend from the base, in manner as represented in iig. 3 of the within-mentioned drawings.

What I claim as' my invention, in a glass article, or vessel, as moulded with a contractilev bottom tubular projection, B, as described, is-

The combination and arrangementtof the open space G, with such projection, and the surrounding base D, the purpose of such space being substantially as speci.

fied.

HENRY WHITNEY.
